The posting

We are looking for a Social Advertising Specialist to help us scale customer acquisition through high-performing paid social campaigns.

In this role, you will build, test, and optimize campaigns across channels such as Instagram, Facebook, TikTok, LinkedIn, and other relevant platforms. Your work will directly contribute to qualified demand, stronger creative performance, better conversion quality, and improved marketing efficiency.

This is a good fit for someone who combines performance marketing expertise with creative judgment, analytical thinking, and a structured experimentation mindset.

About Wellis

Wellis is a fast-growing healthtech scale-up reinventing healthcare. We are building the first truly integrated health platform in the Netherlands, offering on-demand care for everyday health needs such as weight loss, hair loss, sexual health, and more.

Our platform covers the full journey: from diagnosis and medical assessment to prescription and delivery at home. By combining medical expertise, technology, and data, we make healthcare smarter, more accessible, more personal, and easier to use.

We are growing quickly, which means we are building the structures, teams, products, and processes that will help us scale responsibly. You will join an ambitious, international team where ownership is encouraged, collaboration is key, and impact is visible from day one.

About the role & team

As our Social Advertising Specialist, you will join our Marketing team and report directly to the Performance Marketing Lead.

You’ll collaborate cross-functionally—with Content, Design, Data, CRM, Medical, and Customer Care—to ensure our campaigns are engaging, compliant, and tightly integrated into the customer journey.

Your immediate focus will be optimizing paid social performance, building a structured creative testing framework, and refining funnel strategies. Over time, you’ll help establish a scalable, data-backed performance playbook. Your ultimate goal is simple: drive high-quality customer acquisition while keeping CAC, POAS, and Profit contribution on track.

  • Reporting & Learnings: Translate performance data into clear, actionable insights, risks, and next steps for the broader business.

  • A culture of short lines, speed, ownership, and continuous improvement, where pragmatism and impact matter.
  • The opportunity to help build a fast-growing healthtech scale-up from the inside.

Who you are

  • Paid Social Expert: Deep hands-on experience structuring, scaling, and optimizing paid social campaigns against strict commercial targets.
  • Creative & Commercial Thinker: Possess sharp creative judgment—you intuitively know which hooks and messaging build trust and drive action.
  • Data-Driven & Analytical: Fluent in CAC/CPA, POAS, and conversion metrics, using data to prioritize tests and optimize budgets.
  • Systematic Experimenter: Passionate about structured A/B testing and transforming campaign learnings into repeatable growth.
  • Customer-Centric: Deeply understand buyer motivations and friction points, converting those insights into persuasive ad copy and visuals.
  • Cross-Functional Collaborator: High agency and strong ownership—able to seamless align with Design, Data, CRM, and Medical teams.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
